WITILIAM .ANCILE FRY WILLARD'CLARK DARBY, AND THOMAS HENRY KEBSHA'W,

OF PUEBLO, COLORADO.

DEVICE FOR MOLDING CONCRETE WALLS,

Be it known that we, WILLIAM ANCILE FRY, WILLARD CLARK DARBY, and THOMAS HENRY KERSHAW, citizens of the United States, and residents of Pueblo, in the county of Pueblo and State of Colorado,

have invented a new and useful Improve ment in Devices for Molding Concrete -Walls.

, lapsible boxes so they may be removed from the Walls; all arranged so a convenient height of wall, entirely around the building, and all openings and projections may be formed at one time whereupon the molding devices are raised to a proper position to form another section of the walls.

The objects of our invention are; first, to provide means for molding the- Walls of buildings in sections, each section encir-' cling the building thereby giving greatest strength to said walls; second, to provide such molding devices with means for carrying the markings of ornamentation and forms to mold all projections and openings in the walls; third, to provide means for molding hollow walls; and, fourth, to provide such molding devices with means for constructing walls of varying dimensions. We attain these objects by the mechanisms illustrated in the accompanying drawings in which,

Figure 1 is a perspective view, in broken section, showing the parts of our invention in place at the corner of a building. Fig. 2 is a perspective view of the collapsible core box used to form openings within the walls; Fig. 3 is a perspective view of one of the adjusting turnbuckles, with its finger bolts; Fig. 4: is an end elevation showing manner of elevating .our'molds in position to construct an additional section; Fig. 5 is a top,

and Fig. 7 is a perspective view, in broken sectlon, of a portion of the side pieces of the wall mold showing stop plates used in stopping out openings for doors, windows and the like.

Similar. numerals refer to similar throughout the several views.

The side pieces for construction of the wall consist of outside Wall plates 1 and inside Wall plates 2. On the inside of Wall plates 1 and 2- may be placed marking pattern 3 of any desired design whenever it is desired to mark the Walls produced in any manner, and such pattern may be attached to plates 2 as Well as to plates 1. These plates are made in sections of suitable lengths to which are attached anglirons 2 through which are bolts 2" by means of which the ends of the wall plates are brought close together without leaving space or markings and thus the wall plates may be joined together in any desired length as shown inFig. 5; and by means of said angle irons the outside plates 1 may be j oiriedat a corner by means of clamps holding the one portion of the angle iron firmly against plate 1 as shown by clamps l and connecting angle iron 1", Fig. l. -When it is desired to form projections on the wall the same is accomplished by the pattern of desired projections being attached to one of the plates as 1*, Fig. 1;

The plates being attached according to the planof wall designed are held in place and proper position by beams a and turnbuckles 5 on finger bolts 6. Beams are placed the required distance apart in pairs, one beam on each side of the plates, and

parts the turnbuckles and finger bolts are adjusted one near the top of the side. plates 1 and 2 and one at the top of beams 4 which extend some distance above, and by the. adjustment of the turnbuckles said beams are brought into position to bear upon the plates 1 and 2,-said plates being secured to said beams, so that they assume the position desired and the upper turnbuckle serves to push the top of the beams out while the lower turnbuckle serves to pull the lower part of the beams together, and hold them pressing against the plates 1 and 2. When ever projections as 1 occur. in the Wall the said beams 4 are spliced by clamp washers 4 wijzh bolts 4", so as pass around such roje tions and continue the beam. The l inger bolts of said tuinbuckles which fit over the flanges of beams are held in position by set screws 6.

,Whenever it is deslred to make openings in the wall for doors and windows and it is overlap and are provided at the top inner end with clip 11 on sidelate 10 which plate overlaps plate 9 and is slidable thereon with a corresponding like clip at the bottom on plate 10 slldable on plate 9, and avclip 12 attached at the top and inner end of-plate 9 slidable on plate 10 and a corresponding like clip attached at the bottom to plate 9 also slidable on'plate 10; in like manner the opposite side is constructed, plates 18 and 19 overlap and plate 19 has attached at the inner end at top and bottom clips 11 slidable on plate 18 and plate 18 has attached at the inner end at top and bottom clips 12 slidable on plate '19, in this manner mak-' ing the sides formed by plates 9 and 10 and plates 18fand 19 adjustable to varying lengths. At each end and upper part of 8, Fig. 2, a door is attached by hinges respectively. to plate 9 and plate 10, and said door at each cndis composed of plate 13 hinged ,ineach case to plate 9 and-plate 10,. to

which plate 13 is attached by set screws in slots, {p ate 14, so that varyin widths may be obtained. Plate 15 is hinge to the lower end of plate 13 and plate 16 is attached to plate 15 by set screws 1n slots southat varying widths may be obtained; plates 17 are hinged one to the out-er end of each of'the plates 9, 10, 18 and 19, extending from lower part of 13 to bottom of core box 8, Fig. 2; hinged plates 17 are each provided witha knuckle-jointed arm 21, one-end of which is pivotally attached to side plates 9, 10, 18 and 19 respectively and the other end is'attached pivotally to 17 as at 20; rods 7 one of which is near each end and near top of core 'box S-extend through plates 9 and 18 and plates 10 and 19, on each of which rods are placed collars with setscrews 7.

the inner collar to' adjust plates for width desired and the outer collars on each rod to adjust position of core box 8 with respect to wall pieces 1 and 2 as shown in Fig. 1; and

a door 13 composed of two plates slidable and attached by set screws may be attached by hinges to one side of corebox 8 and inside to be used for bracing or stiffening the sides of the core box. The core box is duplicated throughout length of wall by joinin r core boxes as shown in Fig. 2.

e provide derrickframes composed of legs 23 astride the wall to be constructed and beams 24 to which beams are attached pulleys 25 over which cables 26 attached to beams 4, operate to lift the as shown in Fig. 4."

It will thus be seen that to operate our. device the plates 1 are joined to represent one side or outside of wall and plates 2 are joined to make the "face of one side or inside of wall, the corners, are made ,by use of clamps and angle irons, being formed and plates being connected by beams and plates means of angle irons 1, are placed iIl'POSltlOIl around the whole of the wall to be constructed, or any eter nined portion thereof; and the st s are adjusted for window or open spaces desired. The turnbuckles are adjusted to hold the wall plates in place. The respective side plates of core box are adjusted to the desired length and the door 13 and plate 15 are adjusted by means of set screws and slots to the requlred width of space to be formed, when'doors 13 and 13 are opened out at right angles to the attaching sides and the side lates 18-19 are placed against the doors w ere they are held by the adjustable collars with set screws on rods 7, the sides and. doors being thus arranged the lates 17 are opened outwardly and retained in place by knuckle-jointed arms 21, and hinge plate 15 is opened upward and rests on plates 17. The core box 8, being thus set up, is placed between the side wall plates 1 and 2, as in Fig. 1, and is held in place by outer collars and set screws on rods 7, the collars being adjusted to the edges of side plates 1 and 2, and aseries of .core boxes is placed end to end along thev course of the wall between the side plates 1 and 2; with the parts thus in position the space between side plates 1 and 2 and around core boxes is filled with cement material to the top of side plates 1 and 2; thus forming hollow walls except the solid portion that lies above plates 15 which forms a tie between the two portions of the. wall. Upon the space being filled in, the core boxes may be colla sed and removed by pressing inwardly the nuckle-jointed arm 21, thus drawing plates 17 inwardly and permitting plate 15 to drop down'and doors 13 and 13" are then closed inwardly, which releases the side plates 9-'-10. and 18 -19 from pressure against cement material and the whole may be lifted out by rods 7; the turnbuckles are released and'plat'es 1 and 2 released from ressure against the cement material, and bygmea'ns of the derrick and cables, Fig. 4, the whole structure is lifted for the next course, andin practice the core boxes may be lifted along with the side wall plates 1 and 2 -When lifted by cables attached to derrick. ,In the next succeeding course the core boxes Would be so placed as to form core over the part of wall left solid in the preceding course and thus alternate throughoutthe structure.

Having thus described our improvement, We claim,

In a cement wall molding device of the character described comprising side Wall plates in sections attachable, a core box comprising slidably joined side pieces, hinged end door pieces, each hinged end door piece carrying a slidable plate adjustable by means of set screws in slots, a plate hinged to said hinged door end piece carrying a plate adjustable by means of set screws in slots, plates hinged to said slidable side pieces and operatively connected thereto by knuckle-jointed arms,- and rods and collars thereon having set screws in combination W1th said slidable side pieces, all substantlally as descrlbed.
